An idle game where you raise mysterious creatures called "Tasmon" on your desktop.

Tasmons hatch from a mysterious egg on a small island.

Until the egg hatches, do what you like, or you must. The appearance and abilities of the Tasmon that hatches will depend on your actions on the PC.

Even after your Tasmon hatches, you don't need to constantly monitor them.

Simply feed them between tasks or games, and play with them during breaks.

When you're doing something else, they'll go for walks and sleep on their own.

Time in this game only advances while you play.

On days when your PC is off, Tasmon can also rest.

Liven up your desktop by raising a wide variety of Tasmons, and relax with them.

Your Tasmon's powers will increase little by little depending on the type of food they eat and how you care for them.

Once they're strong enough, you can even make them fight.

Battles don't require complex controls and are mostly automatic.

Let's raise a powerful Tasmon!
